2 RANGES of PARAMOTORS PROPELLERS

The PLUG'n'FLY propellers are 100% carbon, the lightest and the strongest on the market, in two sectionable parts, simple to assembly. Those propeller have been chosen and validated by the major engines and paramotors manufacturers.

Exist in 2-blades, 3-blades and 4-blades, in diameters from 115 to 160 cm, for almost all engines.

This type of propellers, with adjustable pitch (pre-adjustment done in E-PROPS workshop), is interesting for engines manufacturers, paramotors manufacturers, champions, and pilots who are looking for the best pitch. As all the E-PROPS propellers, they are very light and the very efficient.

Exist in 2-blades, 3-blades and 4-blades, in diameters from 115 to 160 cm, for almost all engines.

A propeller with a 130 cm diameter will have a higher thrust (some kg) than a 125 cm diameter. It depends on the engine and max RPM.

Examples :

- Engine Polini Thor 250 red 2,8 =>

2-blades propeller PLUG'n'FLY diameter 125 cm = thrust 85 kg

2-blades propeller PLUG'n'FLY diameter 130 cm = thrust 89 kg

- Engine Vittorazi Moster 185 red 2,86 =>

2-blades propeller PLUG'n'FLY diameter 125 cm = thrust 76 kg

2-blades propeller PLUG'n'FLY diameter 130 cm = thrust 80 kg

What is the choice between a 2-blades, a 3-blades or a 4-blades ?

Which propeller would have the best efficiency ?

When the model exists, in the E-Props range, it would be a 4-blades, without doubt.

The more blades, the best efficiency. It is possible to see this in our MODELIZATION PROGRAM. A 4-blades propeller would have a better efficiency, thus would gives the best thrust. This is true for the diameters and the powers used in leisure aviation.

But it is true only if the blade is adapted to the configuration : a blade of a 2-blades propeller which will be assembled on a 3-blades or 4-blades hub do not allow to reach the best performances with such 3- or 4-blades propellers. The universal blade designed for all configurations do not exists, unfortunately. To each propeller exist a different blade geometry, or the effciency will not be the best.

By E-Props, the 4-blades propellers have been designed with a special concept to reduce the noise. It is the QD2 concept : a 4-blades composed of 2 x 2-blades with different angles to reduce the noise and increase the performances.

Noise reduction in comparison with a standard propeller : about 6 decibels.
